DMSO is a dipolar, aprotic, hygroscopic solvent for which a large number of pharmacologic properties have been claimed. Topical DMSO is considered an effective and safe antidote to be used with topical cooling after extravasations of vesicant drugs. A case of toxicity after its use as an antidote is described. Furthermore, the increasing importance of DMSO pharmacology, as its use in haematologic patients is spreading, is reviewed.
